Ōi is one of Japan’s most accomplished pool players, having recently triumphed at the inaugural 2026 Carabao International Open, securing his second World Nineball Tour ranking title. Building on his impressive career, he previously claimed his first WNT ranking crown at the 2024 Taom Maxrack Nineball Helsinki Open and went on to reach the final of the 2025 European Open, further cementing his status among the world’s elite.

The World Pool Masters is one of nineball’s longest-running invitational tournaments. First staged in Plymouth, England in 1993, it has been won by players including Francisco Bustamante, Shane Van Boening and Joshua Filler, giving each new field a place to pursue among the sport’s established champions.
The event’s recent editions have used a straight-knockout format, placing immediate pressure on a select field: one defeat ends a player’s challenge. The 2027 tournament brings together 20 players at Songshan Cultural and Creative Park in Taipei City from 12–14 January, following the Chinese Taipei Open at the same venue.
For the first time, the Masters will feature a two-table arena, with matches from both tables available live on WNT TV. The move to Chinese Taipei opens a new chapter for a competition with more than three decades of history.
